Skin is the largest organ within the human body -- an average adult has around 8 lbs. of skin measuring nearly 22 square feet. Human skin acts as a waterproof barrier, protects other vital organs from damage and is a giant sensory blanket responsible for relaying messages to the brain regarding potential dangers. As with the heart and other organs, taking care of the skin helps maintain its proper function. Pomegranate juice has active medicinal compounds, and one proposed use of this fruit juice is to help protect and maintain healthy skin.
Active Constituents
The primary constituent found within pomegranate juice is ellagic acid. This acid is a polyphenol chemical, which means this compound contains a high concentration of antioxidants. The "Clinical and Experimental Dermatology Journal" reports this compound features anti-wrinkle activity, anti-inflammation properties and various bioactivities aimed at the prevention of chronic diseases. Other compounds found within pomegranate juice include riboflavin, citric acid, boric acid, niacin, thiamine, potassium and calcium.
Function
The "Journal of Nutritional Science and Vitaminology" outlines a study performed by the Research and Development Division of the Kikkoman Corporation where female participants were given 200 mg of ellagic acid, 100 mg of ellagic acid or a placebo dose. Study participants with the highest dose of ellagic acid showcased brightness in the skin and a reduction of freckles and skin discoloring after two to three weeks. Researchers say this suggests the primary active compound of pomegranate juice, ellagic acid, prevents skin pigmentation due to UV radiation. The "Clinical and Experimental Dermatology Journal" also suggests ellagic acid reduces wrinkles and inflammation and prevents collagen degradation by blocking various fibroblasts.
Dosage
The University of Maryland Medical Center suggests 4 to 12 oz. of pomegranate juice per day as part of a healthy diet. No specific dose is recommended for skin health. Make sure the product is 100 percent pomegranate juice with no sugar added to ensure you receive the proper amount of ellagic acid.
Safety Considerations
Prior to taking pomegranate juice, discuss its use with your health care provider, especially if you are taking medications as this juice may cause an adverse reaction. The University of Maryland Medical Center states those with diarrhea should not consume pomegranate, and women who are pregnant should avoid consuming pomegranate extract; however, pomegranate juice is safe for pregnant and lactating women.
